I did another test:
1. Boot computer
2. Load kernel module: modprobe -k em28xx video_debug=1
3. Plug Pinnacle Hybrid Pro Stick (320e)
4. Start xawtv
5. rawrec -c 1 -f s16_le -s 44100 -d /dev/dsp2 |rawplay -c 1 -f s16_le -s 44100
-d /dev/dsp
Now there is no sound. The dmesg so far is:

6. here I open the "Video source" option and select "Television" again.
